Sunlight burned leaves?? Is it irreversable?

Day 13 after sprout-rockwool insertion, leaves were only slightly yellow this morning, (use a 150w LED at night) and lemon juice to lower ph. What am i doing horribly wrong? Is sunlight too much for it?

any way to reverse the effect?

I cannot see the picture you posted.

Did you get the leaves wet when the plant was in strong sunlight? Under my M/H lights if I splash water on the leaves & don't knock it off the light will refract through the liquid & burn the leaves. And no - it won't reverse, but its not the end of the world as long as it isn't too badly burned.
